【摘要】：离散制造业是中国重要产业之一,特别是在作为“世界工厂”的我国,其发展水平的高低,直接影响到我国国民经济。在激烈的市场竞争驱动下,产品的质量、成本、交货期已经成为影响离散制造业核心竞争力的重要因素,而其装配生产线的优化与否,直接影响到这三大因素的好坏。由于该类企业订单批量小品种多、交货期短、随机性问题多等特点,导致装配生产线换产的情况频繁发生；而当前大部分企业只是简单凭经验对装配线进行设计,导致装配线的产出率不高的情况比较普遍。这对企业在降低生产成本、缩短交货期、提高效益等发展方向上制造了很大障碍。所以,对于手工或半手工的离散制造企业,探索一套适用于企业本身特点的考虑人员能力差异的装配生产线优化方法很有必要。本文总结和运用多种关于装配生产线优化的理论和方法,以广东某包装品制造企业为背景,提出考虑人员能力差异因素的装配生产线优化方法。在该研究方法中,首先根据企业的调研情况,充分分析影响装配生产线平衡的因素,以装配线生产节拍最小化为优化目标,构建考虑人员能力差异因素装配生产线优化的数学模型；其次,分别对大小规模的问题提出优化算法,即对小规模问题提出求解精确解的全局优化算法,对大规模问题提出求解近似解的分步求解启发式算法；再次,为评估优化结果的优劣性,提出求解优化结果上下界的衡量方法,并分别利用大小规模算例对其进行分析；最后,根据该企业的实际生产情况,基于上述优化算法,开发设计了适用于该企业装配生产线优化的系统,并用应用实例验证了系统的实用性。
[Abstract]:Discrete manufacturing industry is one of the important industries in China, especially in China as a "world factory", its level of development has a direct impact on our national economy. Driven by the fierce market competition, the quality, cost and delivery time of the products have become an important factor affecting the core competitiveness of discrete manufacturing industry, and the optimization of its assembly line directly affects the quality of these three factors. Because of the characteristics of many small orders, short delivery time and many random problems, the changing production of assembly line occurs frequently. At present, most enterprises simply design assembly lines based on experience. As a result of assembly line output rate is not high situation is more common. This has created a great obstacle to the development of enterprises in reducing production cost, shortening delivery time and improving efficiency. Therefore, it is necessary to explore a set of optimization methods of assembly line which can take into account the difference of personnel ability for the discrete manufacturing enterprises by hand or semi-manual. This paper summarizes and applies a variety of theories and methods about assembly line optimization, taking a packaging manufacturing enterprise in Guangdong as the background, and puts forward an optimization method of assembly line considering the factor of personnel ability difference. In this research method, the factors that affect the balance of assembly line are fully analyzed according to the research situation of the enterprise, and the optimization goal is to minimize the production beat of assembly line. The mathematical model of assembly line optimization considering the factor of personnel ability difference is constructed. Secondly, the optimization algorithm for the problem of size and scale is proposed, that is, the global optimization algorithm for solving the exact solution of small scale problem. A step by step heuristic algorithm for solving approximate solutions is proposed for large-scale problems. Thirdly, in order to evaluate the merits and demerits of optimization results, a method to measure the upper and lower bounds of optimization results is proposed, and an example of large and small scale is used to analyze the heuristic algorithm. Finally, According to the actual production situation of the enterprise, based on the above optimization algorithm, the system suitable for the assembly line optimization of the enterprise is developed and designed, and the practicability of the system is verified by an application example.
